Beit known that we, An'rnnn L. Bnr'rs and ANTI-tony B. FEY, Citizens of the United States, residing at Oincinnatnin the county of Hamilton and State of -.Ohio,-ha.v invented certain new and useful ,Improve ments in Bucket Boxes, of which the following is a specification. w

The invention has to do with welded truck; tanks such as are used for carrying and ve'nding gasoline and oil. An important element of these vehicles is the bucket-box provided at the rear. endof the horizontal tank for holding the buckets, funnels; et'c., forming part of the equipment. The object of'this' invention is to produce a stronger and better appearing bucket-box than heretofore,

well as to improve the construction of the bucket-box itself. Other 'objectsfand fea-.

sheet in this view;

and-side wings 9 with upwardextensions 10.

The sidewingsiare bent forward on the verstiffening with the least extra Fig; 7, is 'a ne1evation' of the 'three-piece top front section with its parts united but Fig.8 is a plan view of the'bottom'sheet section prior to bending; and

7 top extensions'intended for a bucket-boxin" which the upper section of the box conforms to the outline of the tank, the dottedline indicating the outline of the tank.

g The rear portion of the shell of the; tank is marked 1, and the rear head 2. The head, as is customary, is inserted into the shell, somewhat'inwardly of the rear end thereof, and is formed with a rearwardlydirected peripheral flange 3, which is autogenously welded to the inner face of the shell as ind cated at. 4. The shell projectsfor a short Thebody or case of the bucket-box is constructed of comparatively heavy sheet.

metal fabricated in certain sections, which I are joined by autogenous welds produced Ywith a suitablewelding torch or electrically. One of the sections is a backsheet section 7 having an upwardly curved'top edge 8,

tical lines 11, to' form the sides of the box,

and the extensions 10 arecurved toward each other in conformity with the arch of the top edge of the back, the extensions being corner welded to this edge and their end edges being weldedto each other, thus forming anarched top for the'box- On the ends of the wings 9 are lips 12, which are bent along three vertical lines, 13, 14, in, such manner as to form a vertical door-post portion 16-.bent inward at right angles to each side, parallelwiththe back, a door-jamb portion'17 bent backward into the interior of the box, and a door-stop portion 18 bent transversely inward from the door-jamb. In this way a Z-section door-frame. struc-- ture in one piece with the side and back section is produced, anda highv degree of weight is obtained. I

- The back and sides are further formed with bottom flange. lips 19, whichare bent horizontally inward to support a horizontal bottom; sheet 20, which is suitably secured:

in place. On the forward edge of this sheet is a lip 12 like the lips'12, which is bent on the three lines 13 14;, 15, to form a bottom Z-section door-frame structure, the ends of which arewelded to the lower ends of the side members of the door-frame The top of the door-frame is formed by a. top front section, which is best formed of three pieces, a center piece 21, and two side, corner pieces 22. These pieces are formed up separately and welded together, and the section thus produced is then corner welded to the front edge of the top and welded also to the side door-frame members. The pieces are cut with curved upper elges to correspond with the curvature of the top; the

lower edge of the piece 21 is horizontal and the lower edges of the pieces 22 are inclined to correspond to the usual shape of the top of the doors 28. These lower edges are each bent twice on the lines 14*, 15 first backward into the interior of the box and then downward, to complete the door-frame and stiffening structure at the top.

A pair of side-hinged doors 23 is shown, but a top hinged door may be used as well, the two forms of door being well-known.

A wooden lining 2% is constructed within the metal box to keep the contents from rattling and striking sparks, and to afford desirable shelving and partitions. This lining is retained at the front within the doorframing, as is seen in Figs. 3 and d.

The back section is cut with a large opening 25 conforming substantially to the outline of the tank extension 5, but of slightly smaller diameter, so that the edge of the opening projects inward past the edge of the extension, the sheet thus abutting the extension. Pairs of parallel slits are cut in the edge of the opening, and the metal between these slits is bent rearward of the box that is to sav forwardk of the tank forming lugs 26 which extend within the extension 5 and lie against the inner face thereof. The ends of these lugs are then welded to said face of the extension as indicated at 27. The contr ction of cooling draws the back section close against the extension; and to complete a perfectly tight smooth joint the corner between the box back and the extension is soldered along the upper half. Since the welds 27 occur only at intervals they may be partly superposed on the weld i of the tank head, as shown in Fig. 5, without interfering with access to this main weld 1n case of necessity, and the extension 5 can be of minimum length.

The particular form of bucket-box just described is one which projects beyond the perimeter of the tank at the upper part as well as at the sides and bottom. In another form, the box conforms with the tank'substantially over the upper half, and in such case the opening of the back sheet is not reverses entirely within the edges, but is represented by a deep arc.

lVith this construction it is more convenient to make the back section 7 of two pieces which are welded together at their inner ends, below the opening or cut-outs, the construction being otherwise like that previously described, except that over the upper half the box is but-welded to the end of the tank.

The removal of a large or major part of the area of the back section, leaving practically only a frame, reduces to a substantial extent the amount of dead weight that must be carried, in itself an important consideration, but does not weaken the structure of the box, which is so stiffened, strengthened and inherently braced by the welding to the tank and by the manner in which its members are formed and co-operatively related, that the structure is amply capable of withstanding the racking strains to which it is subjected at the rear end of the tank truck.

The conditions affecting one of these bucket boxes are of a severe and peculiar character, and the purpose governing the construction of the several parts and the fabric as a whole is not only to provide a suitable enclosure, but also to obtain, without undue weight, a high degree of resistance to disintegrating forces which act upon a naturally vulnerablepart of the body of a heavy and heavily loaded vehicle, which travels rapidly over roadways of all characters.

The advantages of the present bucket-box result from a number of features. Instead of making the box of a shell and two heads welded to the edges of the shell, as in the Davis Patent 1,248,088, the back sheet section is in one piece with the sides and the top; furthermore, the side members of the door-frame are formed by repeated bendmgs from these side wall portions, greatly stiffening the structure and further avoiding welding at the vertical corner edge It may be noted that this is true of the form shown in Fig. 9, as well as in the form of Figs. 1 to 8, for while in Fig. 9 the back sheet section is shown made for convenience from two pieces welded together at the middle of the back, the effect is the same as if one single piece were employed, the sides and top and the side door frame members being all made continuous with each other and with the back, by bending, and the dihedral angles at 11, 13, 14 and 15 being bends and not welds. In like manner, the 2 section bottom part of the door-frame and door stopis formed integral, by bending, with the bottom sheet, which in turn rests upon flanges 19 integrally bent from the main unit. The top front section also has integrally bent flanges completing the door- 1 ineage frame and "stop, and when formed,- as in Fig. 7, of three pieces, permits of an arched top line of the box being combined with a polygonaltop line of the door and door opening, in a very rigid construction.

It Wlll thus vbe perceived that the invention' involves a manner "of construction and assemblage' of forms and pieces, anda com- 'bination ofbending and welding, to secure great strength in the box'and advantagein manufacture; and likewise an improved" manner of uniting the back of, the box to I the end of the tank.
